Gasoline (p = 0.739 g/cm) is pumped into a car through a 4-inch nozzle at the gas pump. (a) If it takes two minutes to fill a 48-liter tank, what is the volumetric flow rate of the gasoline and how much mass has been added to the tank? (b) If the gasoline mixture has been altered to contain 5% ethanol (p=0.787 g/cm), what is the volumetric flow rate of the liquid and how much mass will have been added to the 48-liter tank in the same two minutes?
